Answer:
Your answers are correct.
Step-by-step explanation:
The equality will be true for odd multiples of π/4, so the last two choices will not show the expression to be <em>not</em> an identity.
When j is reflected across the line of x=1 the j will become j'= 3 , then reflected again across the x - axis the j will become j''= -3. So your answer is -3

Part A,
I would assume the triangles are similar so
6y=4y+18
minus 4y both sides
2y=18
divide 2
y=9
Part B
sub for y
6(9)=54
the angle is 54

4. I actually forgot proofs, let me think
dunno this one
I would say cory is wrong
3rd attachment
5. since 8≠9, it is not a bisector of any sort nor is it equidistant from T and R
answer is point A is not on a bisector
4th attachment
it is not perpendicular in any way
if we assume that TXA=RXA, then the first and last options are right
5th attachment
7.
those 2 triangles are equal because of Side-angle-side
they have to be equal 2x=3x-5
minus 2x both sides
0=x-5
add 5
5=x
x=5
8.
it would be isocelseese
because the 2 sides are equal
